EulerOS Virtualization for ARM 64 3.0.2.0 : cups (EulerOS-SA-2021-2120)

high Nessus Plugin ID 151308

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the cups package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

- In macOS High Sierra before 10.13.5, an issue existed in CUPS. This issue was addressed with improved access restrictions.(CVE-2018-4181)

- It was discovered that CUPS allows non-root users to pass environment variables to CUPS backends. Affected backends use attacker-controlled environment variables without proper sanitization. A local attacker, who is part of one of the groups specified in the SystemGroups directive, could use the cupsctl binary to set SetEnv and PassEnv directives and potentially controls the flow of the affected backend, resulting in some cases in arbitrary code execution with root privileges.(CVE-2018-4180)

- A Incorrect Default Permissions vulnerability in the packaging of cups of SUSE Linux Enterprise Server 11-SP4-LTSS, SUSE Manager Server 4.0, SUSE OpenStack Cloud Crowbar 9 openSUSE Leap 15.2, Factory allows local attackers with control of the lp users to create files as root with 0644 permissions without the ability to set the content. This issue affects: SUSE Linux Enterprise Server 11-SP4-LTSS cups versions prior to 1.3.9. SUSE Manager Server 4.0 cups versions prior to 2.2.7. SUSE OpenStack Cloud Crowbar 9 cups versions prior to 1.7.5. openSUSE Leap 15.2 cups versions prior to 2.2.7. openSUSE Factory cups version 2.3.3op2-2.1 and prior versions.(CVE-2021-25317)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
